You estimate:\n- A quick solution (1 hour) has 60% chance of being optimal\n- More analysis (5 hours) has 90% chance of being optimal\n- The optimal solution saves the client $50,000 vs. the suboptimal one\n\n1. How much analysis should you do?\n2. How would your answer change if you charged $1000/hour?\n3. What if you were doing this for yourself (no billing)?\n4. Generalize: derive a formula for optimal thinking time given problem stakes and thinking cost",
